do you have manual C60 climate control..

or do you have automatic C68 climate control..


does the blower work  when you power it directly?? using something like a remote starter button/switch..

can you narrow down which system.. and perhaps a YEAR..

you could have several issues..

a burned out blower motor..

a burned out blower resistor

dead blower relays

no power to the blower control circuit..

bad control head. or blower switch in the control head...

again.. these all depend on what year and model and climate control type...

different years are wired differently...

most have  pressure switch on the high side (small tube ) of the a/c compressor hoses...

when the high side pressure comes up above  certain point the radiator fans come on...


some cars use  single relay...

some cars use 2 relays..

some care use 3 relays..

and if you don't actually have  corvette.. but something like  toyota... some of those use 4 relays to control the cooling fans...

an exact year might get you a better answer..
